For my money, I'd expect that all game changes would be reflected in the documentation with an updated manual included in each patch.

I would much rather have a living manual than wade through an outdated pdf and any number of addendum files.

That would be a great idea for sure, just doubt anyone will ever do it... The best manual you can prob ever have will be the one you trim down yourself based on experience and notes my guess. Unless of course someone in like a year or so after the intial patches and stuff writes the "Ultimate Guide for WitE" which means they have an insane amount of free time or money...lol!
